Rope adjustment system

Abstract

A cord adjustment system includes: an object comprising at least two pieces; a guide detachably connected to one of the pieces; a turntable adjustment buckle detachably connected to the other of the pieces and comprising a post; and a cord connecting the guide and the post; wherein the turntable adjustment buckle allows the cord to be wound around the post in a fastening direction or unwound from the post in a release direction, wherein when the cord is wound around the post in the fastening direction, the spacing between the pieces decreases, and when the cord is unwound from the post in the release direction, the spacing between the pieces increases.

Claims

1. A cord adjustment system, comprising: An object comprising at least two parts; A guide member is detachably connected to one of the plates; a turntable adjustment buckle includes a first buckle and a second buckle, wherein the first buckle has a first fixing part, a first through hole and a first mating part, the first fixing part is detachably connected to the other of the plates, the second buckle has a post and a second mating part, the second mating part is disposed on the post and matches the first mating part; and a cord passes through the first through hole and connects the guide member and the post; wherein the second buckle is rotatable relative to the first buckle, so that the cord can be wound around the post in a fastening direction or unwound from the post in a releasing direction, when the cord is wound around the post in the fastening direction, the distance between the plates decreases, and when the cord is unwound from the post in the releasing direction, the distance between the plates increases.

2. The cord adjustment system as described in claim 1, wherein, The guide includes a guide body and a guide hook disposed on the guide body. Each of the plates has at least one rope portion, which passes around the guide body and abuts against the guide hook and is limited by the guide hook.

3. The cord adjustment system as described in claim 2, wherein, The guide further includes a limiting body having a T-shaped cross-section and extending outward from the surface of the guide body, and the cord is wound around the limiting body and limited by the limiting body.

4. The cord adjustment system as described in claim 3, wherein, The first fastener further has a rope tail, a through hole and a first rope groove. The first rope groove is defined by the rope tail. The through hole is disposed in the rope tail and communicates with the first rope groove. The rope is wrapped around the limiting body and passes through the through hole to form a first knot. The first knot is accommodated in the first rope groove and cannot pass through the through hole to prevent the rope from falling off from the rope tail.

5. The cord adjustment system as described in claim 2, wherein, The guide further includes a perforation and a receiving groove. The receiving groove is defined by the guide body. The perforation passes through the guide body and connects to the receiving groove. After the rope passes through the perforation, it forms a first knot. The first knot is received in the receiving groove, and the first knot cannot pass through the perforation to prevent the rope from falling off the guide.

6. The cord adjustment system as described in claim 1, wherein, The first fixing part has a fixing body and a fixing hook provided on the fixing body. Each of the pieces has at least one rope portion, which passes around the fixing body and abuts against the fixing hook, and is limited by the fixing hook.

7. The cord adjustment system as described in claim 1, wherein, The second fastener further has a second through hole and a second rope groove. The second rope groove is defined by the column. The second through hole is formed in the column and connects to the second rope groove. The rope is passed through the first through hole and the second through hole in sequence to form a second knot. The second knot is accommodated in the second rope groove and cannot pass through the second through hole to prevent the rope from falling off the column.

8. The cord adjustment system as described in claim 1, wherein, The guide or the first fixing part is detachably connected to the sheet body via a button structure.

9. The cord adjustment system as described in claim 1, wherein, The first matching part has a plurality of positioning slots, and the second matching part has at least one claw accommodated in the positioning slot. The claw is composed of a base end extending outward from the column, a bent body bent in the circumferential direction, and a snap-fit ​​body disposed on the bent body and facing the positioning slot.

10. The cord adjustment system as described in claim 9, wherein, The second fastener further includes an operating part, an assembly body, and an assembly groove. The assembly body is located at the center of the operating part, and the assembly groove is formed by a recess from the surface of one end of the column and matches the assembly body. In this way, the operating part can move together with the column via the assembly body and the assembly groove.

11. The cord adjustment system as described in claim 10, wherein, The first fastener further has a first limiting portion surrounding the first matching portion, and the second fastener further has a second limiting portion. The second limiting portion is located on the inner edge of the operating portion and extends inward. When the set of ligands and the set of matching slots are matched, the second limiting portion is engaged with the first limiting portion, thereby preventing the set of ligands from disengaging from the set of matching slots.

12. The cord adjustment system as described in claim 1, wherein, The first fastener further has a shaft hole, and the column has a shaft portion that is accommodated in the shaft hole, so that the second fastener can rotate relative to the first fastener about the shaft portion as the axis.

13. The cord adjustment system as described in claim 1, wherein, The item is a running vest, hydration vest, or backpack.
